01_GazePointData

[Alberto Melchor]

I am trying to have the tobii 5C device track objects in the 3d space such as cube. I was attempting to remodify scene one gazepoint data. I noticed that there is no code in the script for the layout for gazemap with all the bubbles. Where in this scene do I modify to remove this and replace it with a script to generate a scene with cubes instead of the 2d layout with bubbles.

I notice when I remove Gaze Point Data Example object it removes the background but not the bubbles, but there is not much inside but transform and event trigger.

In Gaze Point Data Example I have removed the Event Trigger component and added my script to create cubes in 3d space. It did generate however the tobii background with all the information about the example, x y coordinates and information whether gaze is detected or not is still there how do I remove this?

Hi @mela501, the easiest way to proceed in this case is to start with a blank unity scene and then import the Tobii Library directly rather than going through our Demo scene.

We provide instructions for this (Step 5 onward) @ https://developer.tobii.com/pc-gaming/unity-sdk/getting-started/

and show explicitly the syntax @ https://developer.tobii.com/pc-gaming/unity-sdk/scripting-api/#tobiiapigetgazepoint

Please go through this and let us know how you get on. Best Wishes.

thank you, I wanted to ask a question about GazeScene01, I wanted to ask about ray casting, aside from the moveable point I also wanted to include a ray casting. I tried to modify the script at ProjectPlaneToWorld but I wanted to ask how I would use the Debug.DrawLine method, the debug.Drawline method was taken from a tutorial but this time I wanted to see how the eyegaze would be implemented. The code below did not display the Raycast Line.

public float maxRayDistance = 25;
private Vector3 ProjectToPlaneInWorld(GazePoint gazePoint)
{
Vector3 gazeOnScreen = gazePoint.Screen;
gazeOnScreen += (transform.forward * VisualizationDistance);
Ray ray = Camera.main.ScreenPointToRay(gazeOnScreen);
RaycastHit hit;
Debug.DrawLine(transform.position, transform.position + gazeOnScreen * maxRayDistance, Color.red);
return Camera.main.ScreenToWorldPoint(gazeOnScreen);
}
